BACKGROUND: Allo-immune mediated lung syndromes (allo-LS) are life-threatening complications after hematopoietic cell transplantation (HCT). Respiratory virus (RV) has been suggested to play a role in the pathogenesis. OBJECTIVE: We studied the relation between RV-DNA/RNA detection in upper/lower airway before HCT and the occurrence of allo-LS. METHODS: We retrospectively analyzed all HCT recipients between 2004 and 2014, in whom Real-Time PCR for RV was done from Nasal-Pharyngeal-Aspirates (NPA) and Broncho-Alveolar- Lavage (BAL) before HCT...

This article reviews the common pulmonary complications seen in the pediatric oncology population and our approach to diagnosis, management, and therapy considerations in this specialized population, including patients receiving chemotherapy, radiation, and hematopoietic stem cell transplantation. Although infections cause the most significant complications in this population, non-infectious complications, including acute lung injury from chemotherapy or radiation, idiopathic interstitial pneumonia, diffuse alveolar hemorrhage, bronchiolitis obliterans, and cryptogenic organizing pneumonia, also occur commonly...

BACKGROUND: Lung transplantation is the only effective treatment for end-stage lung diseases. Bronchiolitis obliterans, which is known as non-infectious chronic lung allograft dysfunction (CLAD) in the new classification, is the greatest threat to long-term survival after lung transplantation. This study investigated the role of leukotriene B4 (LTB4) and montelukast in transplantation-related bronchiolitis obliterans and discussed the pathophysiological significance of LTB4 in chronic rejection...

PURPOSE: To describe the effects of aerosolized antipseudomonals (AAPs) on Pseudomonas (PS) culture positivity, bronchiolitis obliterans syndrome (BOS), and acute cellular rejection (ACR) in lung transplant recipients (LTRs). METHODS: Single-center, retrospective cohort study was performed of adult LTRs treated with either AAP for ≥28 days vs no AAP therapy or AAP therapy <28 days, indexed to a matched median date post lung transplantation (LT). Primary outcome was freedom from PS positivity by positive bronchoalveolar lavage or bronchial wash at 1 year...

Fiberoptic bronchoscopy and transbronchial lung biopsy are currently the gold standard for detection of acute rejection following human lung transplantation (LTx). However, these surveillance procedures are expensive and invasive. Up to now, there are few new methods that have demonstrated clinical utility for detecting early stages of rejection following human lung transplantation. We optimized and technically validated a novel method to quantify donor-derived circulating cell free DNA (DcfDNA) that can be used as an early biomarker for lung allograft rejection...

BACKGROUND: Bronchiolitis obliterans syndrome (BOS) is a clinical manifestation of chronic allograft rejection following lung transplantation. We examined the quantitative measurements of the proximal airway and vessels and pathologic correlations in subjects with BOS. METHODS: Patients who received a lung transplant at the Brigham and Women's Hospital between December 1, 2002 and December 31, 2010 were included in this study. We characterized the quantitative CT measures of proximal airways and vessels and pathological changes...

Tissue fibrosis is the primary cause of long-term graft failure after organ transplantation. In lung allografts, progressive terminal airway fibrosis leads to an irreversible decline in lung function termed bronchiolitis obliterans syndrome (BOS). Here, we have identified an autocrine pathway linking nuclear factor of activated T cells 2 (NFAT1), autotaxin (ATX), lysophosphatidic acid (LPA), and β-catenin that contributes to progression of fibrosis in lung allografts. Mesenchymal cells (MCs) derived from fibrotic lung allografts (BOS MCs) demonstrated constitutive nuclear β-catenin expression that was dependent on autocrine ATX secretion and LPA signaling...

Chronic lung allograft dysfunction (CLAD) remains the major obstacle to long-term survival following lung transplantation (LuTx). Morphologically CLAD is defined by obliterative remodelling of the small airways (bronchiolitis obliterans, BO) as well as a more recently described collagenous obliteration of alveoli with elastosis summarised as alveolar fibroelastosis (AFE). Both patterns are not restricted to pulmonary allografts, but have also been reported following haematopoietic stem cell transplantation (HSCT) and radio chemotherapy (RC)...

BACKGROUND: Patients with non-scleroderma connective tissue-related lung disease (NS-CTLD), including rheumatoid arthritis, idiopathic inflammatory myopathies, Sjögren syndrome, mixed connective tissue disease, and systemic lupus erythematosus, may be at risk for worse outcomes after lung transplantation because of immune dysregulation or extrapulmonary manifestations of their underlying disease. We compared survival, acute and chronic rejection, and extrapulmonary organ dysfunction after transplantation in patients with NS-CTLD and idiopathic pulmonary fibrosis (IPF)...

Transplant-related complications are common after allogeneic hematopoietic stem cell transplantation (allo-HSCT), including graft versus host disease (GVHD). The lungs are frequently affected during the course of allo-HSCT, and among the non-infectious pulmonary complications bronchiolitis obliterans syndrome (BOS) is the most common and considered the only diagnostic manifestation of pulmonary GVHD. BOS is an irreversible obstructive disease that affects the terminal bronchioles, and it is associated with high morbidity and mortality rates...

BACKGROUND: Methotrexate (MTX) is potential change in immunosuppression after lung transplantation that may help to slow down the decline in lung function in bronchiolitis obliterans syndrome (BOS). METHODS: We sought to analyze the safety and efficacy of MTX in patients with BOS, by retrospective case review. RESULTS: Thirty lung allograft patients were treated with MTX for BOS after one bilateral lower lobe, nine single, 16 bilateral, and four heart-lung transplants...

Bronchiolitis obliterans is a small-airway obstructive lung disease for which immunologically mediated pathogenesis is supposed. Frequent association of bronchiolitis obliterans with paraneoplastic pemphigus is well known, but its association with other autoimmune bullous diseases has not been reported except for a case of anti-laminin-332-type mucous membrane pemphigoid in a patient with chronic graft-versus-host disease. We report a case of non-paraneoplastic autoimmune subepidermal bullous disease associated with fatal bronchiolitis obliterans in a patient without transplantation...

With the increasing use of mismatched, unrelated, and granulocyte colony-stimulating factor-mobilized peripheral blood stem cell donor grafts and successful treatment of older recipients, chronic graft-versus-host disease (cGVHD) has emerged as the major cause of nonrelapse mortality and morbidity. cGVHD is characterized by lichenoid changes and fibrosis that affects a multitude of tissues, compromising organ function. Beyond steroids, effective treatment options are limited. Thus, new strategies to both prevent and treat disease are urgently required...

The single most important cause of late mortality after lung transplantation is chronic lung allograft dysfunction (CLAD). However, the pathological development of CLAD was not as simple as previously presumed and subclassification phenotypes, bronchiolitis obliterans syndrome (BOS) and restrictive CLAD (rCLAD), have been introduced. We want to re-investigate how CLAD manifests in the murine orthotopic lung transplant model and investigate the role of interleukin 17A (IL-17A) within this model. Orthotopic LTx was performed in CB57BL/6, IL-17 WT and IL-17 KO mice...

Idiopathic pneumonia syndrome (IPS) is an acute lung dysfunction of non-infectious aetiology and a severe complication following haematopoietic stem cell transplantation (HSCT). Recently, the American Thoracic Society (ATS) updated the concept of IPS and extended the concept to a wider range; it defined IPS as "an idiopathic syndrome of pneumopathy after HSCT, with evidence of widespread alveolar injury and in which infectious aetiologies and cardiac dysfunction, acute renal failure, or iatrogenic fluid overload have been excluded...

Being involved in clinical practice and research concerning chronic lung allograft dysfunction (CLAD) nowadays is an extremely complicated matter. It used to be more simple: When a lung transplant recipient presented with a persistent decline in pulmonary function for which no other cause could be identified, the diagnosis of bronchiolitis obliterans syndrome (BOS) was made. BOS patients were typically obstructive and non-responsive to therapies. Spirometric and pathological findings not consistent with this typical presentation were mostly discarded (1)...

CD59 is a complement regulatory protein that inhibits membrane attack complex formation. A soluble form of CD59 (sCD59) is present in various body fluids and is associated with cellular damage after acute myocardial infarction. Lung transplantation (LTx) is the final treatment for end-stage lung diseases, however overall survival is hampered by chronic lung allograft dysfunction development, which presents itself obstructively as the bronchiolitis obliterans syndrome (BOS). We hypothesized that, due to cellular damage and activation during chronic inflammation, sCD59 serum levels can be used as biomarker preceding BOS development...
